Precision rail guides

The SKF precision rail guides are arranged in pairs and the cage containing the rolling elements is located in between. SKF offers a modular range with ball assemblies (fig. 1), crossed roller assemblies (fig. 2), needle roller assemblies (fig. 3) or slide coating (fig. 4). The modular range combines different guidance principles with exactly the same outer dimensions and drilling hole pattern. This unique feature allows the same external dimensions at a given size range. This results in optimized performance with a wide choice of load carrying capacity, stiffness and operating characteristics.
